160.01 ADOPTION OF ELECTRICAL CODE.
   The 2021 Edition of the National Electrical Code adopted by the National Fire Protection Association is hereby adopted as the electrical code of the City of Denison, Iowa.
(Ord. 1565 – Oct. 23 Supp.)
160.02 COMPLIANCE WITH ELECTRICAL CODE AND CHAPTER.
   All electrical installations, alterations, and repairs shall be made in compliance with the requirements of the National Electrical Code and in compliance with the requirements of this chapter. In the event of conflict between the requirements of said electrical code and the requirements of this chapter, electrical installations, alterations, and repairs shall be made in compliance with the requirements of this chapter.
160.03 CONDUCTORS.
   All conductors, however well insulated, shall always be treated as bare so that under no conditions existing or likely to exist can any short circuit occur and so that all leakage from any conductor or between any conductor and ground shall be reduced to a minimum.
160.04 ELECTRICAL EQUIPMENT.
   In laying out an installation, except for constant current systems, every reasonable effort shall be made to secure distribution centers located in easily accessible places at which points cutouts and switches controlling the various circuits shall be grouped for convenience and safety of operation. The load shall be divided as evenly as possible between branches and all complicated and unnecessary wiring shall be avoided.
160.05 EXIT LIGHTS.
   In all public halls and places where exit lights are required, they shall be on separate circuits from those used for general lighting.
160.06 CONDUIT WORK.
      1.   Except as provided by subsections 2 and 3 of this section, all electrical wires conducting electrical energy in excess of 32 volts in or upon the following specified buildings and structures shall be enclosed in metal conduit or metal raceway.
         A.   All buildings and structures within the fire limits of the City of Denison, Iowa.
         B.   All schools, hospitals, churches, and institutions of every kind for the care or treatment of persons.
         C.   All club houses and social or community center buildings.
         D.   All public and utility buildings.
         E.   All garages with floor space for three or more cars.
         F.   All gasoline service stations.
      2.   Flexible metal conduit or any conduit acceptable under the National Electrical Code may be used in lieu of rigid metal conduit under the following conditions:
         A.   In the remodeling or repair of existing buildings and structures where existing wiring is to be extended or relocated in concealed locations and the use of metal conduit is impractical. In exposed locations in such buildings and structures non-flexible metal raceway may be used.
         B.   For connections to motors, removable reflectors and similar installations requiring frequent removal or adjustment for a distance not in excess of six feet or for any distance acceptable under the Electrical Code.
      3.   In the remodeling or repair of existing one- and two-family dwellings within the fire limits of the City, where existing wiring is to be extended or relocated in concealed locations, Romex cable may be used.
